Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Tribulus terrestris has been traditionally used in various systems of medicine, including Ayurveda and Traditional Chinese Medicine, for enhancing male vitality and treating sexual dysfunction. Historically, it has been considered an aphrodisiac and a "tonic" for improving physical performance and masculinity. The rationale for its use in supporting testosterone levels primarily stems from these traditional beliefs and anecdotal reports, rather than robust scientific validation.

While some animal studies and small-scale human trials have suggested that tribulus may have a mild effect on sexual function and libido, the evidence supporting its ability to significantly increase testosterone levels in humans is weak and inconsistent. Most well-conducted clinical trials have found no significant difference in testosterone levels between individuals taking tribulus supplements and those given a placebo. Systematic reviews and meta-analyses also conclude that tribulus is unlikely to cause clinically meaningful increases in testosterone in healthy men.

Therefore, the use of tribulus for low testosterone is rooted more in tradition than in science. Its popularity in supplements marketed for "testosterone boosting" is better explained by its long-standing reputation rather than by evidence-based outcomes. Users should be aware that despite its traditional use, reliable scientific support for tribulus as a testosterone booster remains limited.
